GEORGE W. NEWMAN, OF CHICAGO, ILLINOIS, ASSIGNOR TO WILSON JONES LOOSE LEAF COMPANY, A CORPORATION OF ILLINOIS.

METHOD OF PRODUCING LOOSE-LEAF-BINDER COVERS.

Application filed July 8, 1922.

To all whom it may concern:

Be it known that I, GEORGE W. NEWMAN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Method for Producing Iioose-Iieaf-Binder Covers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates to a method of producin blanks for forming the covers of loose l eaf binders or books, together with the blank formed by one or more steps thereof.

In the manufacture of covers for loose leaf binders or books, these blanks are usually cut from a sheet of imitation leather or pyroxylin coated fabric or some composition which has fusible properties.

And it is an object of this invention to provide a method for cutting the blanks from the sheet of composition or leather and finishing the raw edges thereof so that the edges will not fringe.

It is also an object of this invention to provide a cover cut on a bias and finished so that the edges will not fringe.

This invention comprises the novel method and article hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawing which illustrates a preferred embodiment of this invention and in which similar reference numerals refer to similar features in the different views.

On the drawings:

Figure 1 is a perspective view of an apparatus for carrying out part of the method.

Figure 2 is a transverse section through an individual blank illustrating the tufted edges.

igure 3- is a broken transverse section upon an enlarged scale of an individual blank illustrating the singed and fused ed es.

Iigure f is a plan view of the blank.

Figure 5 is a fragmentary plan view of a blank with a portion of the upper Surface cut away showing the Weave of the fabric.

Serial No. 573,681.

As shown'on the drawings:

In carrying out my method, I first cut the desired blanks from the roll of coated fabric, upon a bias, that is obliquely to the direction of the fiber as shown in Fig. 5 so that the edges will not become fringed as is the case when the cut is square across the fibre. I then stack a convenient number of cut blanks in superimposed relation with the edges in alinement and compress the same.

I then apply a torch or the like to the edges to singe the fringes and at the same time heat and fuse the coated fabric so that the upper and lower portions of the edges of each individual blank will run together and seal the edge as shown in Fig. 3.

In Fig. 1 is illustrated a V-shaped clamp 1 between the arms of which a plurality of blanks cut on a bias are stacked between a pair of plates 2 which maybe pressed together by a screw 3 threaded into an arm of the clamp. This apparatus may be conveniently used for carrying out the singeing and fusing steps of my method.

It is characteristic of this invention that the cover blanks for the binder are cut obliquely to the direction of the fibre preventing thereby the edges thereof from becoming fringed after use.

I am aware that numerous details of con struction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than nccessitated by the prior art.

I claim as my invention:

1. The method of producing blanks for binder covers from a roll of pyroxylin'coated fabric, which consists in cutting the blanks obliquely to the direction of the fibre, stacking a plurality of blanks in superimposed relation with these edges in alinement, compressing said blanks and singeing, and fusing the edges thereof.

. .2. The method of producing blanks for binder covers from a roll of fabric treated with a fusible composition, which consists in cutting the blanks on a bias, stacking the same in superimposed relation with their ed es in alinement, compressin the same an simultaneously singeing an fusing the edges thereof.
